VALVE-STOPPER FOR BOTTLES.

SPECIFICATION forming part of Letters Patent No. 515,879, dated March 6, 1894.

A ellant's se emtn 25,1893.

To all whom it mag concern).- I

Be it known that I, NATHANIEL F. T. HUNT, of Braintree, in the county of Norfolk and State of Massachusetts,have invented an Imthe bottle inclined, the latter figure illustratingthe action of the tumbler.

The bottle a, has a tube 12 secured upon its mouth, as in my application now pending, Serial No. 482,796, filed August 10, 1898, the purpose of this construction being to form a chamber for the valve 0 and tumbler d, which constitute the main feature of my present invention. After the bottle a has been filled the valve 0 and tumbler cl are applied and the tube 12 then secured in place, and the cork inserted in the mouth of tube 12. Valve 0 is kept in line with the neck of the bottle by wings, and acts to prevent the refilling of the bottle, but allows the contents of the bottle to be poured out when the bottle is uncorked.

The tumbler 01 moves readily in the chamher for the valve and tumbler, (formed by the tube 1) with its shoulder 22" when in place on bottle a) when the bottle is inclined sufficiently to pour out theliquid in it; and will tip by its weight as indicated in Fig. 8 and tend to close valve 0, in case an attempt be made to refill the bottle, by inclining it and partly immersing it in the liquid; thereby practically preventing refilling of the bottle. The shoulder b causes the tumbler to act as a prop, when one edge is against the shoulder and the other against the valve, (see Fig. 8.) The tumbler cl and valve 0 are best made of glass.

It will orally applicable;

be obvious that my invention is genbut for the best results the tube 1), valve 0 Serial No. 486,409. (No model.)

and tumbler d should be used, as the bottlea and tube 12 together constitute a complete bottle, and the tumbler d and valve 0 prevent its being fraudulently refilled; while the tube 7) when in place on bottle a forms a chamber for tumbler d and valve 0, in which these parts are so confined that they operate to the best advantage.

I have shown the tumbler with a single central hole through it and a much flattened sphere in form, but as the hole is to allow of a ready escape of liquid past the tumbler it will be obvious that it is not material that but one passage for the liquid be provided or that it should be in the middle. The escape of the liquid when the passage through the tumbler is a central hole is provided for by the projections c. The central projection c entering the hole through the tumbler, serves as a guide when the bottle is in the position, shown in Fig. 8; but this central projection is unimportant.

' The form of the tumbler may be varied somewhat, but it must always be a flattened sphere, in essence; that is its outline must be circular, and its edges rounding, so that it cannot stand on edge but must always tumble when any attempt is made to hold the bottle so that a line passing through its axis is horizontal or approaching the horizontal.

After the cork has been removed from tube 1), the contents of the bottle can be poured out by tipping the bottle sufficiently, or nearly bottom side up, as in Fig. 7; but the flow will be stopped by tipping the bottle so that the axis of the tumbler is nearly horizontal, because the tumbler will fall sidewise, forcing the valve to its seat, the head of liquid in the bottle acting to resist the seating of the valve being trifling, for it cannot be greater than one-half the diameter of the bottle, when the bottle is full and is less when the bottle is partly filled. All this will be clear if one of my bottles filled with liquid be supposed to be uncorked and laid fiat on a table; in that case as the tumbler cannot stand on edge it tips as indicated in Fig. 8, and it the valve be ground to fit its seat there will be little or no leaking of the liquid from the bottle, even when the bottle is full. This will be clear if the uncorked but filled bottle be supposed to stand upright on the table, and then to be gradually tipped till it is brought on its side, resting on the table; for as soon as the axis of the bottle varies slightly from the vertical the tumbler will tumble so that one edge of it will rest against the valve; and there will be no force but a slight head of liquid to move the valve, for the valve cannot be moved without moving the tumbler also. Moreover any slight leak under the conditions supposed, will cause the air pressure to force the valve close to its seat, the tumbler following it up, and holding it to its seat.

If the attempt be made to refill the bottle, the tumbler will act as above fully explained, except that there will be no head of liquid to resist its constant effort to keep the valve closed.

I am aware of the patent to Jules E. Clerc, No. 487,385, dated December 6, 1892, and disclaim all that is shown in it; for in that patent a rolling ball, and inclined planes for the 1. In combination a vessel; a tube having an interior shoulder; a valve; and a flattened sphere forming a tumbler; the valve and the tumbler being confined in a chamber formed by securing the tube upon the vessel, substantially as shown and described.

2. In combinationa valve with wing guides and a flattened sphere forming a tumbler, both in a chamber at the mouth of a vessel; an interior shoulder in the chamber placed opposite to the mouth of the vessel to act as a stop for one edge of the tumbler, and the wings of the valve in the mouth of the vessel; all substantially as set forth.
